Abstract
Official abstract text for this publication.
An optical flow of depth video of a depth camera imaging a human subject is recognized. An energy field created by motion of the human subject is generated as a function of the optical flow and specified rules of a physical simulation of the virtual environment. The energy field is mapped to a virtual position in the virtual environment. A property of a virtual object in the virtual environment is adjusted based on a plurality of energy elements of the energy field in response to the virtual object interacting with the virtual position of the energy field.
First claim
Opening claim text (preview).
The invention claimed is: 1. On a computing device, a computer-implemented method for controlling a virtual environment, comprising: visually presenting, via a display, a representation of the virtual environment; receiving, from a depth camera, depth video imaging a human subject; recognizing a virtual skeleton that models the human subject with a plurality of virtual joints characterized by three-dimensional positions, the virtual skeleton derived from the depth video; usi…
